NPG+ is new coolant providing dramatic improvements in heat transfer and viscosity that make the new fluid a "pour-in," not requiring changes to cooling system components. Conversion to NPG+ waterless coolant from the use of conventional antifreeze and water coolant mixes, to take advantage of the benefits of non-aqueous engine cooling, is now simple to accomplish. NPG+ waterless coolant virtually eliminates boil over in gasoline or diesel engines - the waterless coolant allows engines to tolerate running hotter, without boiling over, and allows the cooling system to run at very low or no pressure. Because there is no water in the system engines operating with NPG+ will be free from corrosion and electrolysis, and the engines will run well no matter how hard they are driven or how hot or cold the environment is. A blend of non-aqueous ingredients, NPG+ retains all of the benefits of Evans original NPG coolant, while improving upon its thermal conductivity by about 32 percent and reducing its viscosity by about 65 percent. It is perfectly suited for the demands of any hard working engine, and there are no plumbing or pump changes needed to use this coolant. A cooling system according to Evans technology uses a non-water-based, high boiling point coolant (over 350º) and controls the temperature of the coolant substantially below its boiling point. This is in sharp contrast to conventional water based coolant systems that operate near the boiling point of the coolant. In conventional systems, locally generated coolant vapor may not condense but rather form an insulating barrier between the coolant jacket metal and the liquid coolant, causing hot spots to develop. |
